My landing skid was made by layering carbon cloth with Kevlar cloth. The laminates were placed under a heavy weight while they cured. At first I tried 2 layers of carbon and 2 of Kevlar, this was too flexible so I added more until I got to about 6 layers of each. This skid will take a direct hit from nuclear weapons. It is attached with two layers of Kevlar wrapped about 1/3 of the way up each side of the nose cone. Image Insert: 14.57 KB
Here is the servo box for the aileron servos Image Insert: 46.08 KB Here is the wing servo control set up. These are Hitec digital wing servos. I had to make control horns because I lost the ones Phil sent with the wing. Image Insert: 26.92 KB I CA the carbon wing alighment pin to the wingtip so I wouldn’t loose them. I don’t like small loose parts. Image Insert: 11.5 KB The wing joiner rod is CA to the wing center section. This is so I won’t loose them and because it took me a long time to get the tip aligned for and aft with the center section so the ends fit together tightly. With the rod glued in place alignment is not a problem. Image Insert: 11.67 KB Here is the flap servo box. The bottom of this box is 2 layers of 1/8” aircraft plywood epoxied to the top wing skin. The sides of the box are epoxied to the foam. This is important to support the top wing skin on launch. You can see the 5 minute epoxy blobs that hold the servos in place. Hopefully I will be able to get them out by simply cutting the blobs with a craft knife. These are Hitec non-digital wing servos. I will probable have to take one out because it doesn’t center correctly and needs to be fixed. I wish I could afford the digital servos all the way around. The top edge of the servo box is 1/32" below the top surface of the skin so they can be covered with 1/32" plywood. Another roundtoit. Image Insert: 30.36 KB Here is the flap linkage. Again, I had to make the flap control horn out of PC board because I lost Phil’s. Image Insert: 25.61 KB Here is my wing mount. I use 4 wire shielded cable for wing servos because the shielding makes it impervious to picking up radio interference. I have never had a problem with interference with long servo runs with this stuff but it’s downside is it is not as flexible as regular servo wire. The shielding is grounded to the servo ground wire.
